Behaviour
Diet
The diet includes arthropods, and the larvae of wood-boring beetles. Foraging behavior is typical of furnarids - flies to a low position on a branch or tree trunk, and systematically scoots upwards probing for food.
Breeding
It places a few stems and roots in a hole 1.5-4.5 m high in a tree for its nest. The 2 white eggs are incubated by both sexes.
